Camping out in top 100 on a different app

From what i remember i was unable to revenge raid someone on a different version of the app. Which is fine but are people using this to keep themselves in the top 100? I counted 10 that are active and still remain on a previous app. I couldn’t even get on to the game without updating last time seems like maybe that should be the case for everyone. Am i missing something or are these people dodging us?
